Abstract

Method for preparing a superconductive fine powder essentially based on a rare earth, at least one alkaline-earth metal element, at least one transition metal and oxygen, characterised in that it comprises the following stages: a) on the one hand, a rare-earth sol and, on the other hand, a solution of at least one alkaline-earth metal nitrate and of at least one transition metal nitrate are mixed, the pH of the mixture obtained being adjusted to a value such that the said nitrates remain soluble in this mixture; b) drying of the mixture obtained is then carried out; c) the dried product is calcined; d) grinding of the powder is optionally carried out. <??>The invention also relates to the products obtained by the said method.
